Form your discussion by answering the following:

1. Differentiate between a profit center and an investment center.
2. Why might the profit margin of the Franchise segment be larger than the other two segments?
3. What is the source of revenues for the Manufacturing segment?
4. With all of the above in mind, how would you enhance retail sales, which demonstrate the lowest profit margin and return on investment?
